FIELD OF THE DISCLOSURE

This disclosure is in the field digital display devices. In particular, the disclosure relates to devices for use in, and methods of, providing lighting systems for use in digital display systems that can provide controllable biological effects.

BACKGROUND

A wide variety of light emitting devices are known in the art including, for example, incandescent light bulbs, fluorescent lights, and semiconductor light emitting devices such as light emitting diodes (“LEDs”).

Displays for digital content can rely on arrays of pixels that produce individual color points. Displays can be backlit with a white light source, which can be LED-based, and then filtered at the pixel-level to produce colored pixels as desired. Alternatively, displays that are not based on backlighting with white light and filtering downstream can include LEDs at the pixel-level that directly emit light at each colored pixel.

There are a variety of resources utilized to describe the light produced from a light emitting device, one commonly used resource is 1931 CIE (Commission Internationale de l'Éclairage) Chromaticity Diagram. The 1931 CIE Chromaticity Diagram maps out the human color perception in terms of two CIE parameters x and y. The spectral colors are distributed around the edge of the outlined space, which includes all of the hues perceived by the human eye. The boundary line represents maximum saturation for the spectral colors, and the interior portion represents less saturated colors including white light. The diagram also depicts the Planckian locus, also referred to as the black body locus (BBL), with correlated color temperatures, which represents the chromaticity coordinates (i.e., color points) that correspond to radiation from a black-body at different temperatures. Illuminants that produce light on or near the BBL can thus be described in terms of their correlated color temperatures (CCT). These illuminants yield pleasing “white light” to human observers, with general illumination typically utilizing CCT values between 1,800K and 10,000K.

Color rendering index (CRI) is described as an indication of the vibrancy of the color of light being produced by a light source. In practical terms, the CRI is a relative measure of the shift in surface color of an object when lit by a particular lamp as compared to a reference light source, typically either a black-body radiator or the daylight spectrum. The higher the CRI value for a particular light source, the better that the light source renders the colors of various objects it is used to illuminate.

Color rendering performance may be characterized via standard metrics known in the art. Fidelity Index (Rf) and the Gamut Index (Rg) can be calculated based on the color rendition of a light source for 99 color evaluation samples (“CES”). The 99 CES provide uniform color space coverage, are intended to be spectral sensitivity neutral, and provide color samples that correspond to a variety of real objects. Rf values range from 0 to 100 and indicate the fidelity with which a light source renders colors as compared with a reference illuminant. In practical terms, the Rf is a relative measure of the shift in surface color of an object when lit by a particular lamp as compared to a reference light source, typically either a black-body radiator or the daylight spectrum. The higher the Rf value for a particular light source, the better that the light source renders the colors of various objects it is used to illuminate. The Gamut Index Rg evaluates how well a light source saturates or desaturates the 99 CES compared to the reference source.

LEDs have the potential to exhibit very high power efficiencies relative to conventional incandescent or fluorescent lights. Most LEDs are substantially monochromatic light sources that appear to emit light having a single color. Thus, the spectral power distribution of the light emitted by most LEDs is tightly centered about a “peak” wavelength, which is the single wavelength where the spectral power distribution or “emission spectrum” of the LED reaches its maximum as detected by a photo-detector. LEDs typically have a full-width half-maximum wavelength range of about 10 nm to 30 nm, comparatively narrow with respect to the broad range of visible light to the human eye, which ranges from approximately from 380 nm to 800 nm.

In order to use LEDs to generate white light, lighting systems have been provided that include two or more LEDs that each emit a light of a different color. The different colors combine to produce a desired intensity and/or color of white light. For example, by simultaneously energizing red, green and blue LEDs, the resulting combined light may appear white, or nearly white, depending on, for example, the relative intensities, peak wavelengths and spectral power distributions of the source red, green and blue LEDs. The aggregate emissions from red, green, and blue LEDs typically provide poor color rendering for general illumination applications due to the gaps in the spectral power distribution in regions remote from the peak wavelengths of the LEDs.

White light may also be produced by utilizing one or more luminescent materials such as phosphors to convert some of the light emitted by one or more LEDs to light of one or more other colors. The combination of the light emitted by the LEDs that is not converted by the luminescent material(s) and the light of other colors that are emitted by the luminescent material(s) may produce a white or near-white light.

LED lamps have been provided that can emit white light with different CCT values within a range. Such lamps utilize two or more LEDs, with or without luminescent materials, with respective drive currents that are increased or decreased to increase or decrease the amount of light emitted by each LED. By controllably altering the power to the various LEDs in the lamp, the overall light emitted can be tuned to different CCT values. The range of CCT values that can be provided with adequate color rendering values and efficiency is limited by the selection of LEDs.

The spectral profiles of light emitted by white artificial lighting can impact circadian physiology, alertness, and cognitive performance levels. Bright artificial light can be used in a number of therapeutic applications, such as in the treatment of seasonal affective disorder (SAD), certain sleep problems, depression, jet lag, sleep disturbances in those with Parkinson's disease, the health consequences associated with shift work, and the resetting of the human circadian clock. Artificial lighting may change natural processes, interfere with melatonin production, or disrupt the circadian rhythm. Blue light may have a greater tendency than other colored light to affect living organisms through the disruption of their biological processes which can rely upon natural cycles of daylight and darkness. Exposure to blue light late in the evening and at night may be detrimental to one's health. Some blue or royal blue light within lower wavelengths can have hazardous effects to human eyes and skin, such as causing damage to the retina.

Significant challenges remain in providing LED lamps that can provide white light across a range of CCT values while simultaneously achieving high efficiencies, high luminous flux, good color rendering, and acceptable color stability. It is also a challenge to provide lighting apparatuses that can provide desirable lighting performance while allowing for the control of circadian energy performance.

FURTHER DISCLOSURE

The present disclosure may be understood more readily by reference to the following detailed description taken in connection with the accompanying figures and examples, which form a part of this disclosure. It is to be understood that this disclosure is not limited to the specific devices, methods, applications, conditions or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular exemplars by way of example only and is not intended to be limiting of the claimed disclosure. Also, as used in the specification including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. The term “plurality”, as used herein, means more than one. When a range of values is expressed, another exemplar includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another exemplar. All ranges are inclusive and combinable.

The term “circadian-stimulating energy characteristics” refers to any characteristics of a spectral power distribution that may have biological effects on a subject. In some aspects, the circadian-stimulating energy characteristics of aspects of the lighting systems of this disclosure can include one or more of CS, CLA, EML, BLH, CER, CAF, LEF, circadian power, circadian flux, and the relative amount of power within one or more particular wavelength ranges.

It is to be appreciated that certain features of the disclosure which are, for clarity, described herein in the context of separate exemplar, may also be provided in combination in a single exemplary implementation. Conversely, various features of the disclosure that are, for brevity, described in the context of a single exemplary implementation, may also be provided separately or in any subcombination. Further, reference to values stated in ranges include each and every value within that range.

The 1931 CIE Chromaticity diagram is a two-dimensional chromaticity space in which every visible color is represented by a point having x- and y-coordinates, also referred to herein as (ccx, ccy) coordinates. Fully saturated (monochromatic) colors appear on the outer edge of the diagram, while less saturated colors (which represent a combination of wavelengths) appear on the interior of the diagram. The term “saturated”, as used herein, means having a purity of at least 85%, the term “purity” having a well-known meaning to persons skilled in the art, and procedures for calculating purity being well-known to those of skill in the art. The Planckian locus, or black body locus (BBL), is known to those of skill in the art and follows the color an incandescent black body would take in the chromaticity space as the temperature of the black body changes from about 1000K to 10,000 K. The black body locus goes from deep red at low temperatures (about 1000 K) through orange, yellowish white, white, and finally bluish white at very high temperatures. The temperature of a black body radiator corresponding to a particular color in a chromaticity space is referred to as the “correlated color temperature.” In general, light corresponding to a correlated color temperature (CCT) of about 2700 K to about 6500 K is considered to be “white” light. In particular, as used herein, “white light” generally refers to light having a chromaticity point that is within a 10-step MacAdam ellipse of a point on the black body locus having a CCT between 2700K and 6500K. However, it will be understood that tighter or looser definitions of white light can be used if desired. For example, white light can refer to light having a chromaticity point that is within a seven step MacAdam ellipse of a point on the black body locus having a CCT between 2700K and 6500K. The distance from the black body locus can be measured in the CIE 1960 chromaticity diagram, and is indicated by the symbol Δuv, or DUV or duv as referred to elsewhere herein. If the chromaticity point is above the Planckian locus the DUV is denoted by a positive number; if the chromaticity point is below the locus, DUV is indicated with a negative number. If the DUV is sufficiently positive, the light source may appear greenish or yellowish at the same CCT. If the DUV is sufficiently negative, the light source can appear to be purple or pinkish at the same CCT. Observers may prefer light above or below the Planckian locus for particular CCT values, and light above or below the Planckian locus may be more or less suitable for use in displaying digital content on display systems in different settings or operational modes. DUV calculation methods are well known by those of ordinary skill in the art and are more fully described in ANSI C78.377, American National Standard for Electric Lamps-Specifications for the Chromaticity of Solid State Lighting (SSL) Products, which is incorporated by reference herein in its entirety for all purposes. The CIE Standard Illuminant D65 illuminant is intended to represent average daylight and has a CCT of approximately 6500K and the spectral power distribution is described more fully in Joint ISO/CIE Standard, ISO 10526:1999/CIE 5005/E-1998, CIE Standard Illuminants for Colorimetry, which is incorporated by reference herein in its entirety for all purposes.

The color points described in the present disclosure can be within color-point ranges defined by geometric shapes on the 1931 CIE Chromaticity Diagram that enclose a defined set of ccx, ccy color coordinates. It should be understood that any gaps or openings in any described or depicted boundaries for color-point ranges should be closed with straight lines to connect adjacent endpoints in order to define a closed boundary for each color-point range.

The light emitted by a light source may be represented by a point on a chromaticity diagram, such as the 1931 CIE chromaticity diagram, having color coordinates denoted (ccx, ccy) on the X-Y axes of the diagram. A region on a chromaticity diagram may represent light sources having similar chromaticity coordinates.

The ability of a light source to accurately reproduce color in illuminated objects can be characterized using the color rendering index (“CRI”), also referred to as the CIE Ra value. The Ra value of a light source is a modified average of the relative measurements of how the color rendition of an illumination system compares to that of a reference black-body radiator or daylight spectrum when illuminating eight reference colors R1-R8. Thus, the Ra value is a relative measure of the shift in surface color of an object when lit by a particular lamp. The Ra value equals 100 if the color coordinates of a set of test colors being illuminated by the illumination system are the same as the coordinates of the same test colors being irradiated by a reference light source of equivalent CCT. For CCTs less than 5000K, the reference illuminants used in the CRI calculation procedure are the SPDs of blackbody radiators; for CCTs above 5000K, imaginary SPDs calculated from a mathematical model of daylight are used. These reference sources were selected to approximate incandescent lamps and daylight, respectively. Daylight generally has an Ra value of nearly 100, incandescent bulbs have an Ra value of about 95, fluorescent lighting typically has an Ra value of about 70 to 85, while monochromatic light sources have an Ra value of essentially zero. Light sources for general illumination applications with an Ra value of less than 50 are generally considered very poor and are typically only used in applications where economic issues preclude other alternatives. The calculation of CIE Ra values is described more fully in Commission Internationale de l'Éclairage. 1995. Technical Report: Method of Measuring and Specifying Colour Rendering Properties of Light Sources, CIE No. 13.3-1995. Vienna, Austria: Commission Internationale de l'Êclairage, which is incorporated by reference herein in its entirety for all purposes. In addition to the Ra value, a light source can also be evaluated based on a measure of its ability to render a saturated red reference color R9, also known as test color sample 9 (“TCS09”), with the R9 color rendering value (“R9 value”). Light sources can also be evaluated based on a measure of ability to render additional colors R10-R15, which include realistic colors like yellow, green, blue, Caucasian skin color (R13), tree leaf green, and Asian skin color (R15), respectively. Light sources can further be evaluated by calculating the gamut area index (“GAI”). Connecting the rendered color points from the determination of the CIE Ra value in two dimensional space will form a gamut area. Gamut area index is calculated by dividing the gamut area formed by the light source with the gamut area formed by a reference source using the same set of colors that are used for CRI. GAI uses an Equal Energy Spectrum as the reference source rather than a black body radiator. A gamut area index related to a black body radiator (“GAIBB”) can be calculated by using the gamut area formed by the blackbody radiator at the equivalent CCT to the light source.

The ability of a light source to accurately reproduce color in illuminated objects can be characterized using the metrics described in IES Method for Evaluating Light Source Color Rendition, Illuminating Engineering Society, Product ID: TM-30-15 (referred to herein as the “TM-30-15 standard”), which is incorporated by reference herein in its entirety for all purposes. The TM-30-15 standard describes metrics including the Fidelity Index (Rf) and the Gamut Index (Rg) that can be calculated based on the color rendition of a light source for 99 color evaluation samples (“CES”). The 99 CES provide uniform color space coverage, are intended to be spectral sensitivity neutral, and provide color samples that correspond to a variety of real objects. Rf values range from 0 to 100 and indicate the fidelity with which a light source renders colors as compared with a reference illuminant. Rg values provide a measure of the color gamut that the light source provides relative to a reference illuminant. The range of Rg depends upon the Rf value of the light source being tested. The reference illuminant is selected depending on the CCT. For CCT values less than or equal to 4500K, Planckian radiation is used. For CCT values greater than or equal to 5500K, CIE Daylight illuminant is used. Between 4500K and 5500K a proportional mix of Planckian radiation and the CIE Daylight illuminant is used, according to the following equation:

${{S_{r,M}\left( {\lambda,T_{t}} \right)} = {{\frac{5500 - T_{t}}{1000}{S_{r,P}\left( {\lambda,T_{t}} \right)}} + {\left( {1 - \frac{5500 - T_{t}}{1000}} \right)\;{S_{r,D}\left( {\lambda,T_{t}} \right)}}}},$ where T_(t) is the CCT value, S_(r,M)(λ,T_(t)) is the proportional mix reference illuminant, S_(r,P)(λ,T_(t)) is Planckian radiation, and S_(r,D)(λ,T_(t)) is the CIE Daylight illuminant.

Circadian illuminance (CLA) is a measure of circadian effective light, spectral irradiance distribution of the light incident at the cornea weighted to reflect the spectral sensitivity of the human circadian system as measured by acute melatonin suppression after a one-hour exposure, and CS, which is the effectiveness of the spectrally weighted irradiance at the cornea from threshold (CS=0.1) to saturation (CS=0.7). The values of CLA are scaled such that an incandescent source at 2856K (known as CIE Illuminant A) which produces 1000 lux (visual lux) will produce 1000 units of circadian lux (CLA). CS values are transformed CLA values and correspond to relative melotonian suppression after one hour of light exposure for a 2.3 mm diameter pupil during the mid-point of melotonian production. CS is calculated from

${CS} = {❘{0.7{\left( {1 - \frac{1}{1 + \left( \frac{CLA}{355.7} \right)^{\bigwedge 1.126}}} \right).}}}$ The calculation of CLA is more fully described in Rea et al., “Modelling the spectral sensitivity of the human circadian system,” Lighting Research and Technology, 2011; 0: 1-12, and Figueiro et al., “Designing with Circadian Stimulus”, October 2016, LD+A Magazine, Illuminating Engineering Society of North America, which are incorporated by reference herein in its entirety for all purposes. Figueiro et al. describe that exposure to a CS of 0.3 or greater at the eye, for at least one hour in the early part of the day, is effective for stimulating the circadian system and is associated with better sleep and improved behavior and mood.

Equivalent Melanopic Lux (EML) provides a measure of photoreceptive input to circadian and neurophysiological light responses in humans, as described in Lucas et al., “Measuring and using light in the melanopsin age.” Trends in Neurosciences, January 2014, Vol. 37, No. 1, pages 1-9, which is incorporated by reference herein in its entirety, including all appendices, for all purposes. Melanopic lux is weighted to a photopigment with λmax 480 nm with pre-receptoral filtering based on a 32 year old standard observer, as described more fully in the Appendix A, Supplementary Data to Lucas et al. (2014), User Guide: Irradiance Toolbox (Oxford 18 Oct. 2013), University of Manchester, Lucas Group, which is incorporated by reference herein in its entirety for all purposes. EML values are shown in the tables and Figures herein as the ratio of melanopic lux to luminous flux, with luminous flux considered to be 1000 lumens. It can be desirable for biological effects on users to provide illumination having higher EML in the morning, but lower EML in the late afternoon and evening.

Blue Light Hazard (BLH) provides a measure of potential for a photochemical induced retinal injury that results from radiation exposure. Blue Light Hazard is described in IEC/EN 62471, Photobiological Safety of Lamps and Lamp Systems and Technical Report IEC/TR 62778: Application of IEC 62471 for the assessment of blue light hazard to light sources and luminaires, which are incorporated by reference herein in their entirety for all purposes. A BLH factor can be expressed in (weighted power/lux) in units of μW/cm²/lux.

In some aspects the present disclosure relates to lighting devices and methods to provide light having particular vision energy and circadian energy performance. Many figures of merit are known in the art, some of which are described in Ji Hye Oh, Su Ji Yang and Young Rag Do, “Healthy, natural, efficient and tunable lighting: four-package white LEDs for optimizing the circadian effect, color quality and vision performance,” Light: Science & Applications (2014) 3: e141-e149, which is incorporated herein in its entirety, including supplementary information, for all purposes. Luminous efficacy of radiation (“LER”) can be calculated from the ratio of the luminous flux to the radiant flux (S(λ)), i.e. the spectral power distribution of the light source being evaluated, with the following equation:

${{LER}\left( \frac{lm}{W} \right)} = {683\left( \frac{lm}{W} \right){\frac{\int{{V(\lambda)}{S(\lambda)}d\lambda}}{\int{{S(\lambda)}d\;\lambda}}.}}$ Circadian efficacy of radiation (“CER”) can be calculated from the ratio of circadian luminous flux to the radiant flux, with the following equation:

${CE{R\left( \frac{blm}{W} \right)}} = {683\left( \frac{blm}{W} \right){\frac{\int{{C(\lambda)}{S(\lambda)}d\lambda}}{\int{{S(\lambda)}d\;\lambda}}.}}$ Circadian action factor (“CAF”) can be defined by the ratio of CER to LER, with the following equation

$\left( \frac{blm}{lm} \right) = {\frac{{CER}\left( \frac{blm}{W} \right)}{{LER}\left( \frac{lm}{W} \right)}.}$ The term “blm” refers to biolumens, units for measuring circadian flux, also known as circadian lumens. The term “lm” refers to visual lumens. V(λ) is the photopic spectral luminous efficiency function and C(λ) is the circadian spectral sensitivity function. The calculations herein use the circadian spectral sensitivity function, C(λ), from Gall et al., Proceedings of the CIE Symposium 2004 on Light and Health: Non-Visual Effects, 30 Sep.-2 Oct. 2004; Vienna, Austria 2004. CIE: Wien, 2004, pp 129-132, which is incorporated herein in its entirety for all purposes. By integrating the amount of light (milliwatts) within the circadian spectral sensitivity function and dividing such value by the number of photopic lumens, a relative measure of melatonin suppression effects of a particular light source can be obtained. A scaled relative measure denoted as melatonin suppressing milliwatts per hundred lumens may be obtained by dividing the photopic lumens by 100. The term “melatonin suppressing milliwatts per hundred lumens” consistent with the foregoing calculation method is used throughout this application and the accompanying figures and tables.

The ability of a light source to provide illumination that allows for the clinical observation of cyanosis is based upon the light source's spectral power density in the red portion of the visible spectrum, particularly around 660 nm. The cyanosis observation index (“COI”) is defined by AS/NZS 1680.2.5 Interior Lighting Part 2.5: Hospital and Medical Tasks, Standards Australia, 1997 which is incorporated by reference herein in its entirety, including all appendices, for all purposes. COI is applicable for CCTs from about 3300K to about 5500K, and is preferably of a value less than about 3.3. If a light source's output around 660 nm is too low a patient's skin color may appear darker and may be falsely diagnosed as cyanosed. If a light source's output at 660 nm is too high, it may mask any cyanosis, and it may not be diagnosed when it is present. COI is a dimensionless number and is calculated from the spectral power distribution of the light source. The COI value is calculated by calculating the color difference between blood viewed under the test light source and viewed under the reference lamp (a 4000 K Planckian source) for 50% and 100% oxygen saturation and averaging the results. The lower the value of COI, the smaller the shift in color appearance results under illumination by the source under consideration.

The ability of a light source to accurately reproduce color in illuminated objects can be characterized by the Television Lighting Consistency Index (“TLCI-2012” or “TLCI”) value Qa, as described fully in EBU Tech 3355, Method for the Assessment of the Colorimetric Properties of Luminaires, European Broadcasting Union (“EBU”), Geneva, Switzerland (2014), and EBU Tech 3355-si, An Introduction to Spectroradiometry, which are incorporated by reference herein in their entirety, including all appendices, for all purposes. The TLCI compares the test light source to a reference luminaire, which is specified to be one whose chromaticity falls on either the Planckian or Daylight locus and having a color temperature which is that of the CCT of the test light source. If the CCT is less than 3400 K, then a Planckian radiator is assumed. If the CCT is greater than 5000 K, then a Daylight radiator is assumed. If the CCT lies between 3400 K and 5000 K, then a mixed illuminant is assumed, being a linear interpolation between Planckian at 3400 K and Daylight at 5000 K. Therefore, it is necessary to calculate spectral power distributions for both Planckian and Daylight radiators. The mathematics for both operations is known in the art and is described more fully in CIE Technical Report 15:2004, Colorimetry 3^(rd) ed., International Commission on Illumination (2004), which is incorporated herein in its entirety for all purposes.

Displays

Aspects of the present inventions relate to display systems that are adapted to produce and display color(s) at the pixel level that can be used to help in inducing and/or regulating a circadian rhythm cycle in a person looking at the displays or otherwise proximate the display. The display systems may be computer displays or television displays. The lighting system for the display systems pixels may be arranged to produce colors of the pixels in the display that effect the circadian rhythm over the course of time. The lighting system may be adapted to generate a circadian-inducing blue frequency of light (e.g. cyan, energy at and/or near 485 nm) that causes activity associated with ‘waking’ the person through the circadian cycle (e.g. effecting, causing, or maintaining a wakeful and alert state in the viewer by enabling melatonin suppression by exciting the Intrinsically photosensitive retinal ganglion cells (ipRGCs)). It may also be adapted to reduce the circadian-inducing blue frequency over time to reduce the ‘waking’ effect. The lighting system may further be adapted with two or more separate blue frequencies such that either or both may be used to generate the blue in the pixels of the display. One of the blue frequencies may be a standard blue color (e.g. substantial energy around approximately 450 nm, a narrow band emission around approximately 450 nm) such that the display pixel generates standard display colors and another blue frequency may be a circadian-inducing blue (e.g. a cyan emission, substantial energy around approximately 485 nm, a narrow or broad band emission around approximately 485 nm) that is designed to effect the circadian rhythm in a more significant way by waking the person. With such a display, the display pixel colors can be changed from standard colors to represent colors accurately, according to display color standards, to display colors that are similar but not necessarily standard colors to generate an effect of the person's circadian rhythm. While the non-standard blue pixels may not be standard and may not display computer generated content in accordance with a standard color pallet, in many situations the colors may be acceptable by a user because the colors may still be acceptable while also inducing a circadian rhythm to awaken the person while using the display in the special color mode.

The circadian-inducing blue may have significant energy at a longer wavelength than the typical blue used in a display. The inventors have appreciated that longer wavelengths in the blue and cyan regions (e.g. wavelengths between the typical display blue and typical display green) can be used to both generate acceptable colors in the computer-generated content and also have a greater effect on a person's circadian rhythm. In embodiments, the energy may be provided in a narrow band (e.g. a typical LED narrow band emission spectra with a maximum energy between 460 nm and 500 nm, 460 nm and 480 nm, 470 nm and 480 nm, or 490 nm and 500 nm). In embodiments, the energy may be more broadly spread (e.g. through the use of a phosphor or quantum dot structure) such that there is significant energy produced in the region between 460 nm and 500 nm. In such broad width systems the maximum energy may or may not fall within the 460 nm to 500 nm region. For example, the peak may be at or near the typical display blue of 450 nm and also have significant energy in the 460 nm to 500 nm region. The significant energy may be an intensity of more than 10%, 20%, 30%, 40%, or 50% of the maximum energy. That significant energy may fall within the regions of 460 and 470 nm, 470 nm and 480 nm, or 490 nm and 500 nm for example.

A computer display according to the principles of the present inventions may include a micro-LED array where the micro-LED array includes a pixel array formed of micro-LEDs including red, green and blue generating LEDs. In embodiments, the blue LED may be a circadian rhythm inducing blue LED (as described herein). If only three colors are arranged in the pixel array, the circadian-inducing blue for the pixel may not fall within the standard color gamut for the display but will generally generate acceptable colors while effecting the circadian rhythm. In embodiments, the pixel array includes two different color generating blue LEDs, one with a standard color for the display and one that may not be within the standard color gamut for display but that is adapted to effect the circadian rhythm to induce a waking effect. This arrangement would include four colors per pixel in the pixel array of the micro-LED array. In embodiments, the computer display includes only a portion of micro-LEDs with the circadian rhythm effecting blue. The micro-LED pixels may be built with different color generating LEDs, white LEDs with filters, LEDs with phosphors, etc.

In embodiments, the circadian-inducing blue microLED may have a narrow emission characteristic where substantially all of the energy is produced over 120 nm or so and having a full width at half maximum (FWHM) of about 40 nm. FIG. 3a illustrates and example spectral power distribution of such a microLED. In embodiments, the circadian-inducing blue microLED may have a broader emission characteristic. FIG. 3c illustrates one such example spectral power distribution. The broader emission may be developed by adding a phosphor to the microLED system, by using a number of narrow band emission microLEDs, etc. In embodiments, a filter may be associated with the microLED. For example, the desired blue color point may include an emission band that is broader than is achievable through a single narrow emission microLED so a phosphor or multiple narrow band LEDs may be used to broaden the emission and then a filter may be used to cut the broader emission down to the desired amount.

A standard color computer display may use a blue LED with a narrow emission characteristic, such as is illustrated in FIG. 3b . In embodiments, the standard blue may be replaced with a broader band blue, such as is illustrated in FIG. 3d , to add some cyan to the emission (i.e. slightly longer wavelength energy). This configuration may also include a filter to cut the long tail but maintain some emission in the circadian blue emission region.

A computer display according to the principles of the present inventions may include an LCD backlit pixel array. Generally, an LCD backlit display has a backlight that generates a broadband of colors (e.g. white LEDs, white fluorescent) or one that generates narrow bands of color (e.g. red, green, and blue LEDs). Manufactures have typically adopted an arrangement where the backlight is a broadband white LED based system and each pixel of the LCD array is associated with a colored filter (e.g. red, green and blue) to produce the full color gamut for each pixel of the display. In embodiments, the LCD pixel array includes filters to produce three colors per pixel based on a backlighting system that produces white light. The pixel filters filter the white light into red, green and blue. The backlight also generally produces a constant amount of light and the LCD's at each sub pixel color are changed to regulate the intensity of the color of the sub pixel (e.g. 256 steps based on a polarization setting at the sub pixel level). In embodiments, the blue filter is adapted to transmit light that is more effective at effecting the circadian rhythm (e.g. 485 nm). In embodiments, each pixel includes a fourth filter for a fourth sub pixel color. The fourth pixel uses a circadian blue pass filter such that light transmitting the sub pixel filter effects the circadian cycle in a more significant way than light passing through a standard blue filter in the pixel array. With the fourth filter configuration, the display may be set to use one and/or the other color of blue to form the blue in the pixels.

In other embodiments, the backlight produces red, green and blue in a sequence and only one LCD is used per pixel position such that the one LCD will turn on in sequence with the desired corresponding required color for the pixel. The sequential lighting system may than include a circadian-inducing blue color to effect the circadian rhythm. The sequential lighting system may further include two different colors of blue (e.g. standard blue and circadian blue) and the sequence cycles through all four colors. In embodiments, the circadian blue color may or may not be included in every cycle of the sequence. Reducing the number of cycles involves may have an effect on the perceived combined color of the pixel and of the effect of the circadian rhythm.

In embodiments of the LCD configuration(s), the backlight may be modified to include enhanced emission at the circadian blue region. For example, a cyan LED may be included in the backlight itself such that it produces enough emission in the circadian blue region that it can generate adequate color for display and effect on the person's circadian rhythm. The backlight may include a broadband emission source (e.g. as illustrated in FIG. 3c ) or a narrow emission source (e.g. as illustrated in FIG. 3a ) for this purpose. The filter associated with the circadian blue pixels can then be adjusted to transmit the desired bandwidth of light in the region. Traditionally, the backlights used in a display do not produce much emission in this desired region so changing the lighting system to include more emission in this region may be desirable.

A computer display according to the principles of the present inventions may include an OLED pixel array where the OLED array includes a pixel array formed of OLED sub pixels. The OLEDs may including red, green and blue generating OLEDs. In other embodiments, the OLEDs may produce white light and include filters to pass only the particular color desired for the sub pixel. In embodiments, the blue OLED or filter may be adapted to produce a circadian rhythm inducing blue color. If only three colors are arranged in the pixel array, the blue for the pixel may not fall within the standard color for the display but will generally generate acceptable colors while effecting the circadian rhythm. In embodiments, the pixel array may include two different color blue OLEDs, one with a standard color for the display and one that may not be within the standard color gamut for display but that is adapted to effect the circadian rhythm wake cycle. This arrangement would include four colors per pixel in the pixel array of the OLED array. In embodiments, the computer display includes only a portion of OLEDs with the circadian rhythm effecting blue.

In embodiments, the circadian-inducing OLED may produce a broadband of light in the region and be filtered. In embodiments, the circadian-inducing OLED may produce a narrow band emission and possibly be filtered or not.

Aspects of the present inventions relate to the inclusion of more than three standard colors in a computer display pixel array. The more than three colors may include the addition of a color(s) that is intended to provide a display that is switchable between a standard color gamut and a modified color gamut. The modification to the pixel colors may be adapted to produce pixel colors that can effect a person's circadian rhythm while maintaining the display as an effective computer display for the presentation of digital content. A computer processor 107 associated with the display 106 may be used, either automatically (e.g. based on sensed conditions, based on time of day, based on a schedule) or through a user interface, to switch between the two modes. Such a system may also be operated in a mode where both a standard blue and circadian blue are operated simultaneously or through a rapid switching mode (e.g. pulse width modulation to regulate the apparent intensity of each one). The modified color pixel array may be regulated by the computer system to change the pixel colors over time to assist in regulating the person's circadian cycle. The control system may further operate based on data sources 105 that describe the user of the display (e.g. wearable sensors, sleep sensors, as described herein).

FIG. 1 illustrates some examples of computer displays 102 in various configurations. Each of the configurations includes an array of pixels 106 positioned and controlled to display computer-generated content. One configuration is a desktop computer display 102 a. The desktop configuration includes a peripheral 104 (e.g. keyboard, mouse, drawing pad, Bluetooth connected device, WiFi connected device). The desktop, or any other configuration, may receive data from personal devices (e.g. a user's fitbit, sleep sensor) and adjust the color and/or intensity of the light emitted by the pixels 106. Device 102 b is a small touch screen device (e.g. phone, pda). Device 102 c is a tablet device, which may have a touch screen. The display could also be a television, which may be an Internet device, radio receiver device, cable TV device, satellite TV device, etc.

FIG. 2 illustrates various examples of circadian lighting pixel constructions that may be built into a display in accordance with the principles of the present inventions. These examples are simplified examples of the basic construction of the various display technologies at a pixel level. The three examples presented are the microLED 200, OLED 230, and backlit LCD 240. Each of these examples uses a pixel technology that generates light at the pixel level that is outside of the normal display color gamut and at a color point or frequency that is known to effect a person's circadian rhythm.

A microLED based computer display may be based on an array of microLED pixels 200. Each micoLED pixel 200 in the area of the display may include different color producing microLEDs 200, electrodes 208 to power and control each microLED in each pixel, and a substrate 208. Each of the microLEDs may emit light of a particular color based on the materials used in the construction of the microLED. As a secondary example, the microLED(s) may be arranged to irradiate a phosphor for color conversion or they may be arranged to transmit light through a filter. In embodiments, the microLEDs in the pixel may be red, green and circadian blue. The circadian blue may be a blue outside of the normal blue gamut that is used in a display. It may be a blue with spectral characteristics of the circadian lighting systems disclosed herein. In a configuration where only three colors are included in the pixel, the color gamut of the display may always be outside of the standard display gamut. This may be acceptable to a user that is less concerned about the exact color of displayed content and more concerned with receiving a light that effects the user's circadian rhythm while still having reasonable colors produced. In another embodiment, the pixel may include four colors: red, green, standard display blue and circadian blue. This configuration lends itself to a control system that can switch between the standard blue and the circadian blue. The circadian blue may be used in the morning hours, for example, and then the display may switch to the standard blue in later hours. In yet later hours, the standard blue may be turned down to further reduce the stimulation of the circadian rhythm. The two blues may fade in and out in a synchronized fashion. Both may be on at one time to reduce the circadian blue as the system transitions to the standard blue.

An OLED based computer display may be based on an array of OLED pixels 230. The OLED pixel 230 may have three separately controllable OLEDs 212 in each pixel. Each one may emit a similar color (e.g. white) and each one may be optically associated with a different colored filter 211 to generate red, green and circadian blue. In an alternate construction, each OLED emitter may generate its own color (e.g. through a different material, through a phosphor conversion). Each OLED pixel may be constructed with electrodes 214 to power and control each color and a substrate 216. In embodiments, the color set includes a circadian blue (e.g. as described herein). In embodiments, the color set has only three colors, including the circadian blue, and the display produces colors outside of the standard display color gamut. In embodiments, the color set has four colors, including a standard blue and a circadian blue, such that a control system could choose which blue to activate and control as described herein.

A backlit LCD based computer display may be based on an array of backlit LCD pixels 240. The construction of the LCD display may include liquid crystals 206 for multiple channels at each pixel where each liquid crystal in the pixel is associated with a filter that filters the light from a backlight 210. In this configuration, the backlight 210 makes white light and the filters cut the white light into a particular color, generally red, green and blue. In embodiments, the blue filter in the color filter layer 210 is a circadian blue color filter. In embodiments, the filter layer 210 includes two blue filters, associated with two separate liquid crystals: one for circadian blue and one for the standard display blue. In embodiments, the color set includes a circadian blue (e.g. as described herein). In embodiments, the filter color set has only three colors, including the circadian blue, and the display produces colors outside of the standard display color gamut. In embodiments, the filter color set has four colors, including a standard blue and a circadian blue, such that a control system could choose which blue to activate and control.

In embodiments, the LCD pixels may be arranged with a backlight 210 that sequentially cycles through separate colors and the liquid crystal layer in this arrangement may only have one liquid crystal per pixel and it may not include a filter layer. As the backlight sequences through its colors the liquid crystal can be turned on to emit the correct color. By quickly cycling through the colors the user's eye can integrate the color and perceive it as a combined color. For example, leaving the liquid crystal in the ‘on’ or transmit mode and cycling very quickly between red and blue of equal intensity can cause the person to perceive the pixel as purple. In such a construction, the backlight 210 may include a circadian blue emitter(s). In embodiments, the backlight 210 includes both a standard display blue and a circadian blue.

Another aspect of the present inventions relates to a computer display edge lighting system or peripheral. An edge lighting system may surround the computer display and emit light that effects the circadian rhythm of a person using or proximate the computer display. The edge lighting system may include a lighting system similar to the display lighting systems described herein or a panel lighting system as described herein. The edge lighting system may be coordinated with the pixels of the display (e.g. through a computer system associated with both devices). It may otherwise be controlled separately (e.g. as described herein).

Types of Circadian Lighting Systems for Display Systems

Lighting systems that may be used in display systems in accordance with the principles of the present inventions include, for example, 2-channel, 3-channel, 4-channel, 5-channel, or 6-channel LED-based color-tuning systems. Individual channels within the multi-channel systems may have particular color points and spectral power distributions for the light output generated by the channel. As used herein, the term “channel” refers to all the components in a light-generating pathway from an LED (microLED, OLED) through any filtering or other components until the light exits the display system.

In some implementations, 2-channel systems can be used having two white light channels. The two white light channels can be those described more fully in U.S. Provisional Patent Application No. 62/757,664, filed Nov. 8, 2018, entitled “Two-Channel Tunable Lighting Systems with Controllable Equivalent Melanopic Lux and Correlated Color Temperature Outputs,” and International Patent Application No. PCT/US2019/013356, filed Jan. 11, 2019, entitled “Two-Channel Tunable Lighting Systems With Controllable Equivalent Melanopic Lux And Correlated Color Temperature Outputs” the entirety of which is incorporated herein for all purposes.

White Light Channels

In some aspects, the present disclosure provides for display systems that incorporate two white lighting channels, which can be referred to herein as a first lighting channel and a second lighting channel. The white lighting channels can be used to backlight a display system that utilizes color filtering in order to generate a digital display.

In some aspects, the present disclosure provides first lighting channels for use in lighting systems. The first lighting channels can have first color points with CCT values between about 4000K and about 6500K. In some implementations, the first color point can have a CCT of about 4000K.

In certain implementations, the first lighting channel can have one or more LEDs having an emission with a first peak wavelength of about 450 nm.

In some implementations, the first lighting channel can have a first color point with a CCT value of about 4000K. The first lighting channel can have a first color point with a color-point range 304A can be defined by a polygonal region on the 1931 CIE Chromaticity Diagram defined by the following ccx, ccy color coordinates: (0.4006, 0.4044), (0.3736, 0.3874), (0.3670, 0.3578), (0.3898, 0.3716), which correlates to an ANSI C78.377-2008 standard 4000K nominal CCT white light with target CCT and tolerance of 3985±275K and target duv and tolerance of 0.001±0.006, as more fully described in American National Standard ANSI C78.377-2008, “Specifications for the Chromaticity of Solid State Lighting Products,” National Electrical Manufacturers Association, American National Standard Lighting Group, which is incorporated herein in its entirety for all purposes. In some implementations, suitable color-point ranges for the first color point can be described as MacAdam ellipse color ranges in the 1931 CIE Chromaticity Diagram color space, as illustrated schematically in FIG. 14, which depicts a color-point range 402, the black body locus 401, and a line 403 of constant ccy coordinates on the 1931 CIE Chromaticity Diagram. In FIG. 14, MacAdam ellipse ranges are described with major axis “a”, minor axis “b”, and ellipse rotation angle θ relative to line 403. In some implementations, the color-point range for the first color point can be range 304B, an embodiment of color range 402, and can be defined as a single 5-step MacAdam ellipse with center point (0.3818, 0.3797) with a major axis “a” of 0.01565, minor axis “b” of 0.00670, with an ellipse rotation angle θ of 52.70°, shown relative to a line 403.

In further implementations, the first color point can be within the color-point ranges described in Table 57 for the selected boundary for each nominal CCT value. In other implementations, the color-point range for the first color point can be a region on the 1931 CIE Chromaticity Diagram defined by a polygon connecting the (ccx, ccy) coordinates (0.0.3670, 0.3575), (0.3737, 0.3875), (0.4007, 0.4047), and (0.3898, 0.3720). In yet further implementations, the color-point range for the first color point can be a region on the 1931 CIE Chromaticity Diagram defined by a 4-step MacAdam ellipse centered at 3985K CCT and duv=+0.9845. In other implementations, the color-point range for the first color point can be a region on the 1931 CIE Chromaticity Diagram defined by a polygon connecting the (ccx, ccy) coordinates (0.3703, 0.3590), (0.3851, 0.3679), (0.3942, 0.3972), and (0.3769, 0.3864).

In some implementations, the first lighting channel can have certain spectral power distributions. Some aspects of some exemplary first lighting channels are shown in Table 44. Aspects of the spectral power distributions for the exemplary first lighting channels shown in Table 44 and an average of the exemplary first lighting channels (shown as “Exemplary 1st channels avg”) are provided in Tables 46, 48, 50, 52, and 53, which show the ratios of spectral power within wavelength ranges, with an arbitrary reference wavelength range selected for each exemplary first lighting channel or average thereof and normalized to a value of 100.0, except for Table 53, in which the values are normalized to a value of 1.000. In certain implementations, the first lighting channel can have a first spectral power distribution with spectral power in one or more of the wavelength ranges other than the reference wavelength range increased or decreased within 30% greater or less, within 20% greater or less, within 10% greater or less, or within 5% greater or less than the values shown in Tables 46, 48, 50, 52, and 53. In some implementations, the first lighting channel can have a spectral power distribution that falls between the minimum (shown as “min”) and maximum (shown as “max”) values in each of the wavelength ranges as shown in one or more of the Tables 46, 48, 50, 52, and 53. In further implementations, the first lighting channel can have a spectral power distribution that falls between values 5% less, 10% less, 20% less, or 30% less than the minimum (shown as “min”) and values 5% more, 10% more, 20% more, or 30% more than the maximum (shown as “max”) values in each of the wavelength ranges as shown in one or more of the Tables 46, 48, 50, 52, and 53. FIGS. 5, 9, 10, and 12 depict aspects of first spectral power distributions for the exemplary first lighting channels described herein. FIG. 12 depicts a spectral power distribution 1600 for the exemplary lighting channel “5000K Ch1” listed in Table 44 and further characterized elsewhere herein. FIG. 10 depicts a spectral power distribution 1400 for the exemplary lighting channel “4000K Ch3” listed in Table 44 and further characterized elsewhere herein. FIG. 9 depicts a spectral power distribution 1300 for the exemplary lighting channel “4000K Ch2” listed in Table 44 and further characterized elsewhere herein. FIG. 9 depicts a spectral power distribution 900 for the exemplary lighting channel “4000K Ch4” listed in Table 44 and further characterized elsewhere herein. FIG. 5 further depicts some exemplary wavelength ranges 901A, 901B, 901C, 901D, and 901E, which correspond to the wavelength ranges shown in Table 53. As shown in Table 53, in some implementations, first lighting channels may have particular spectral power values within one or more of wavelength ranges 901A, 901B, 901C, 901D, and 901E, or other wavelength ranges not depicted in FIG. 5 or shown in Table 53 but described elsewhere herein.

In some aspects, the first lighting channel can have a first white light having a first color point with a CCT and EML value that falls within a range of possible pairings of CCT and EML values, also referred to herein as a CCT-EML range. A suitable CCT-EML range 1710 for first lighting channels of the present disclosure is shown graphically in FIG. 13, which also shows exemplary point pairings of CCT and EML for the exemplary first lighting channels shown in Table 3. Tables 1 and 2 show CCT and EML values for color points generated by some commercially-available fixed-CCT LED-driven white light systems having Ra values of approximately 80.

Second Lighting Channels

In some aspects, the present disclosure provides second lighting channels for use in lighting systems. The second lighting channels can have second color points with CCT values between about 1800K and about 2700K. In some implementations, the first color point can have a CCT of about 2400K. In some implementations, the first color point can have a CCT of about 1800K, about 1900K, about 2000K, about 2100K, about 2200K, about 2300K, about 2400K, about 2500K, about 2600K, or about 2700K.

In some implementations, the second lighting channel can have one or more LEDs having an emission with a second peak wavelength of between about 380 nm and about 420 nm. In certain implementations, the second lighting channel can have one or more LEDs having an emission with a second peak wavelength of about 410 nm. In some aspects, the use of a different peak wavelength for the LEDs in the second lighting channel in comparison to the LEDs in the first lighting channel can contribute to the desired performance of the lighting systems of the disclosure.

In some implementations of the present disclosure, the second lighting channel can produce light having a second color point within a suitable color-point range. In certain implementations, the second color point can be within the color-point ranges described in Table 57 for the selected boundary for each nominal CCT value. In some implementations, the second color point can be within a color-point range defined by a region bounded by a polygon connecting the (ccx, ccy) coordinates on the 1931 CIE Chromaticity Diagram of (0.4593, 0.3944), (0.5046, 0.4007), (0.5262 0.4381), and (0.4813 0.4319). In further implementations, the second color point can be within a color-point range defined by a region bounded by a 4-step MacAdam ellipse centered at 2370K CCT value and duv=−0.3.

In implementations utilizing LEDs that emit substantially saturated light at wavelengths between about 360 nm and about 535 nm, the display systems can include suitable recipient luminophoric mediums for each LED in order to produce light having color points within the suitable blue color ranges 301A-F, red color ranges 302A-D, cyan color ranges 303A-E, violet color ranges 1301, 1302, and yellow color ranges 1401, 1402 described herein. The light emitted by each lighting channel (from each LED string, i.e., the light emitted from the LED(s and associated recipient luminophoric medium together can have a suitable spectral power distribution (“SPD” having spectral power with ratios of power across the visible wavelength spectrum from about 380 nm to about 780 nm or across the visible and near-visible wavelength spectrum from about 320 nm to about 800 nm. While not wishing to be bound by any particular theory, it is speculated that the use of such LEDs in combination with recipient luminophoric mediums to create unsaturated light within the suitable color ranges 301A-F, 302A-D, 303A-E, 1301, 1302, 1401, and 1402 provides for improved color rendering performance for white light across a predetermined range of CCTs from a single display systems. Further, while not wishing to be bound by any particular theory, it is speculated that the use of such LEDs in combination with recipient luminophoric mediums to create unsaturated light within the suitable color ranges 301A-F, 302A-D, 303A-E, 1301, 1302, 1401, and 1402 provides for improved light rendering performance, providing higher EML performance along with color-rendering performance, for white light across a predetermined range of CCTs from a single display systems. Some suitable ranges for spectral power distribution ratios of the lighting channels of the present disclosure are shown in Tables 1-4 and 7-15. The Tables show the ratios of spectral power within wavelength ranges, with an arbitrary reference wavelength range selected for each color range and normalized to a value of 100.0 except where indicated otherwise.

In some implementations, the lighting channels of the present disclosure can each product a colored light that falls between minimum and maximum values in particular wavelength ranges relative to an arbitrary reference wavelength range. Tables 1, 2, and 7-15 show some exemplary minimum and maximum spectral power values for the blue, red, short-blue-pumped cyan, long-blue-pumped cyan, yellow, and violet channels of the disclosure. In certain implementations, the blue lighting channel can produce light with spectral power distribution that falls within the values between Blue minimum 1 and Blue maximum 1 in the wavelength ranges shown in Table 1, Table 2, or both Tables 1 and 2. In some implementations, the red lighting channel can produce light with spectral power distribution that falls within the values between Red minimum 1 and Red maximum 1 in the wavelength ranges shown in Table 1, Table 2, or both Tables 1 and 2. In some implementations, the red channel can produce red light having a spectral power distribution that falls within the ranges between the Exemplary Red Channels Minimum and the Exemplary Red Channels Maximum in the wavelength ranges shown in one or more of Tables 7-9. In some implementations, the short-blue-pumped cyan can fall within the values between Short-blue-pumped cyan minimum 1 and Short-blue-pumped cyan maximum 1 in the wavelength ranges shown in Table 1, Table 2, or both Tables 1 and 2. In other implementations, the short-blue-pumped cyan can fall within the values between Short-blue-pumped cyan minimum 1 and Short-blue-pumped cyan maximum 2 in the wavelength ranges shown in Table 1. In some implementations, the Long-Blue-Pumped Cyan lighting channel can produce light with spectral power distribution that falls within the values between Long-Blue-Pumped Cyan minimum 1 and Long-Blue-Pumped Cyan maximum 1 in the wavelength ranges shown in Table 1, Table 2, or both Tables 1 and 2. In some implementations, the yellow channel can produce yellow light having a spectral power distribution that falls within the ranges between the Exemplary Yellow Channels Minimum and the Exemplary Yellow Channels Maximum in the wavelength ranges shown in one or more of Tables 13-15. In some implementations, the violet channel can produce violet light having a spectral power distribution that falls within the ranges between the Exemplary Violet Channels Minimum and the Exemplary Violet Channels Maximum in the wavelength ranges shown in one or more of Tables 10-12. While not wishing to be bound by any particular theory, it is speculated that because the spectral power distributions for generated light with color points within the blue, long-blue-pumped cyan, short-blue-pumped cyan, yellow, and violet color ranges contains higher spectral intensity across visible wavelengths as compared to lighting apparatuses and methods that utilize more saturated colors, this allows for improved color rendering for test colors other than R1-R8.

Luminescent Materials and Luminophoric Mediums

Blends of luminescent materials can be used in luminophoric mediums having the desired saturated color points when excited by their respective LED strings including luminescent materials such as those disclosed in co-pending application PCT/US2016/015318 filed Jan. 28, 2016, entitled “Compositions for LED Light Conversions”, the entirety of which is hereby incorporated by this reference as if fully set forth herein. Traditionally, a desired combined output light can be generated along a tie line between the LED string output light color point and the saturated color point of the associated recipient luminophoric medium by utilizing different ratios of total luminescent material to the encapsulant material in which it is incorporated. Increasing the amount of luminescent material in the optical path will shift the output light color point towards the saturated color point of the luminophoric medium. In some instances, the desired saturated color point of a recipient luminophoric medium can be achieved by blending two or more luminescent materials in a ratio. The appropriate ratio to achieve the desired saturated color point can be determined via methods known in the art. Generally speaking, any blend of luminescent materials can be treated as if it were a single luminescent material, thus the ratio of luminescent materials in the blend can be adjusted to continue to meet a target CIE value for LED strings having different peak emission wavelengths. Luminescent materials can be tuned for the desired excitation in response to the selected LEDs used in the LED strings, which may have different peak emission wavelengths within the range of from about 360 nm to about 535 nm. Suitable methods for tuning the response of luminescent materials are known in the art and may include altering the concentrations of dopants within a phosphor, for example. In some implementations of the present disclosure, luminophoric mediums can be provided with combinations of two types of luminescent materials. The first type of luminescent material emits light at a peak emission between about 515 nm and about 590 nm in response to the associated LED string emission. The second type of luminescent material emits at a peak emission between about 590 nm and about 700 nm in response to the associated LED string emission. In some instances, the luminophoric mediums disclosed herein can be formed from a combination of at least one luminescent material of the first and second types described in this paragraph. In implementations, the luminescent materials of the first type can emit light at a peak emission at about 515 nm, 525 nm, 530 nm, 535 nm, 540 nm, 545 nm, 550 nm, 555 nm, 560 nm, 565 nm, 570 nm, 575 nm, 580 nm, 585 nm, or 590 nm in response to the associated LED string emission. In preferred implementations, the luminescent materials of the first type can emit light at a peak emission between about 520 nm to about 555 nm. In implementations, the luminescent materials of the second type can emit light at a peak emission at about 590 nm, about 595 nm, 600 nm, 605 nm, 610 nm, 615 nm, 620 nm, 625 nm, 630 nm, 635 nm, 640 nm, 645 nm, 650 nm, 655 nm, 670 nm, 675 nm, 680 nm, 685 nm, 690 nm, 695 nm, or 700 nm in response to the associated LED string emission. In preferred implementations, the luminescent materials of the first type can emit light at a peak emission between about 600 nm to about 670 nm. Some exemplary luminescent materials of the first and second type are disclosed elsewhere herein and referred to as Compositions A-F. Table 6 shows aspects of some exemplar luminescent materials and properties.

Blends of Compositions A-F can be used in luminophoric mediums having desired saturated color points when excited by respective LED strings in the lighting channels of the disclosure. In some implementations, one or more blends of one or more of Compositions A-F can be used to produce luminophoric mediums. In some preferred implementations, one or more of Compositions A, B, and D and one or more of Compositions C, E, and F can be combined to produce luminophoric mediums. In some preferred implementations, the encapsulant for luminophoric mediums comprises a matrix material having density of about 1.1 mg/mm3 and refractive index of about 1.545 or from about 1.4 to about 1.6. In some implementations, Composition A can have a refractive index of about 1.82 and a particle size from about 18 micrometers to about 40 micrometers. In some implementations, Composition B can have a refractive index of about 1.84 and a particle size from about 13 micrometers to about 30 micrometers. In some implementations, Composition C can have a refractive index of about 1.8 and a particle size from about 10 micrometers to about 15 micrometers. In some implementations, Composition D can have a refractive index of about 1.8 and a particle size from about 10 micrometers to about 15 micrometers. Suitable phosphor materials for Compositions A, B, C, and D are commercially available from phosphor manufacturers such as Mitsubishi Chemical Holdings Corporation (Tokyo, Japan), Intematix Corporation (Fremont, Calif.), EMD Performance Materials of Merck KGaA (Darmstadt, Germany), and PhosphorTech Corporation (Kennesaw, Ga.).

In some aspects, the circadian-inducing blue light in the display systems can have circadian-stimulating energy characteristics that lead to biological effects in users. The circadian-inducing blue, and overall light emissions including the circadian-inducing blue, can have a first circadian-stimulating energy characteristic related to the associated first spectral power distribution of the circadian-inducing blue or overall light emissions, while light emissions from the non-circadian-inducing blue and related overall light emissions can have a second circadian-stimulating energy characteristic related to the associated second spectral power distribution of the circadian-inducing blue or overall light emissions.

In further aspects of the present disclosure, the first and second circadian-stimulating energy characteristics can relate to spectral energy within particular wavelength ranges. In some implementations, spectral energy concentrations within particular wavelength ranges can lead to biological effects by providing photostimulation to intrinsically photosensitive retinal ganglion cells (ipRGCs), which express melanopsin, a photopigment that can respond to light directly, and can be associated with non-image-forming functions such as circadian photoentrainment and pupil-size control in addition to some image-forming functions. ipRGCs are sensitive to light at wavelengths between about 400 nm and about 600 nm, with a peak sensitivity and response to light with wavelengths around 480 nm to 490 nm. In certain implementations, the first circadian-stimulating energy characteristic and the second circadian-stimulating energy characteristic can be the percentage of the spectral power in the first spectral power distribution and the second spectral power distribution, respectively, between a first wavelength value and a second wavelength value, forming a particular wavelength range therein greater than the first wavelength value and less than or equal to the second wavelength value. In some implementations, the first wavelength value can be about 400 nm, about 410 nm, about 420 nm, about 430 nm, about 440 nm, about 450 nm, about 460 nm, about 470 nm, about 480 nm, about 490 nm, about 500 nm, about 510 nm, about 520 nm, about 530 nm, about 540 nm, about 550, about 560 nm, about 570 nm, about 580 nm, about 590 nm, or about 600 nm. In some implementations, the second wavelength value can be about 410 nm, about 420 nm, about 430 nm, about 440 nm, about 450 nm, about 460 nm, about 470 nm, about 480 nm, about 490 nm, about 500 nm, about 510 nm, about 520 nm, about 530 nm, about 540 nm, about 550, about 560 nm, about 570 nm, about 580 nm, about 590 nm, about 600 nm, or about 610 nm. In certain implementations, the first wavelength value can be 440 nm and the second wavelength value can be 490 nm, with the particular wavelength range being 440<λ≤490 nm, as shown for values for the exemplary first and second lighting channels shown in Table 3, which shows the percent spectral energy in the range 440<λ≤490 nm in comparison to the total spectral energy in the range 380<λ≤780 nm. In further implementations, other first and second wavelength values can be selected for the first circadian-stimulating energy characteristic and the second circadian-stimulating energy characteristic of the percentages of the spectral power in the first spectral power distribution and the second spectral power distribution between the first and second wavelength values, including but not limited to wavelength ranges (in nm) from about 400 to about 410, about 410 to about 420, about 420 to about 430, about 430 to about 440, about 440 to about 450, about 450 to about 460, about 460 to about 470, about 470 to about 480, about 480 to about 490, about 490 to about 500, about 500 to about 510, about 510 to about 520, about 520 to about 530, about 530 to about 540, about 540 to about 550, or about 550 to about 560.

In certain implementations, one or more of the circadian-stimulating energy characteristics of the lighting systems can be EML values of the first, second, and third white light. In some aspects of the present disclosure, the lighting systems can provide a ratio of a first EML value of the first spectral power distribution to a second EML value of the second spectral power distribution. In some implementations, the ratio of the first EML value to the second EML value can be between about 2.0 and about 5.5, between about 3.0 and about 5.0, between about 2.8 and about 3.8, between about 2.6 and about 3.3, between about 4.0 and about 5.5, between about 4.5 and about 5.5, between about 5.5 and about 6.5, between about 6.5 and about 7.5, between about 7.5 and about 8.5, between about 8.5 and about 9.5, between about 2.0 and about 10.0, between about 3.0 and about 10.0, between about 4.0 and about 10.0, between about 5.0 and about 10.0, between about 6.0 and about 10.0, between about 7.0 and about 10.0, between about 8.0 and about 10.0, or between about 9.0 and about 10.0. In further implementations, the ratio of the first EML value to the second EML value can be about 2.0, about 2.1, about 2.2, about 2.3, about 2.4, about 2.5, about 2.6, about 2.7, about 2.8, about 2.9, about 3.0, about 3.1, about 3.2, about 3.3, about 3.4, about 3.5, about 3.6, about 3.7, about 3.8, about 3.9, about 4.0, about 4.1, about 4.2, about 4.3, about 4.4, about 4.5, about 4.6, about 4.7, about 4.8, about 4.9, about 5.0, about 5.1, about 5.2, about 5.3, about 5.4, about 5.5, about 5.6, about 5.7, about 5.8, about 5.9, about 6, about 6.1, about 6.2, about 6.3, about 6.4, about 6.5, about 6.6, about 6.7, about 6.8, about 6.9, about 7, about 7.1, about 7.2, about 7.3, about 7.4, about 7.5, about 7.6, about 7.7, about 7.8, about 7.9, about 8, about 8.1, about 8.2, about 8.3, about 8.4, about 8.5, about 8.6, about 8.7, about 8.8, about 8.9, about 9, about 9.1, about 9.2, about 9.3, about 9.4, about 9.5, about 9.6, about 9.7, about 9.8, about 9.9, or about 10.0.

In certain implementations, the first spectral power distribution has a first circadian-stimulating energy characteristic, and the second spectral power distribution has a second circadian-stimulating energy characteristic. In some implementations, the first circadian-stimulating energy characteristic can be a first percentage, the first percentage comprising the percentage of the spectral power between 380 nm and 780 nm in the first spectral power distribution between 440 nm and 490 nm. In certain implementations, the second circadian-stimulating energy characteristic can be a second percentage, the second percentage comprising the percentage of the spectral power between 380 nm and 780 nm in the second spectral power distribution between 440 nm and 490 nm. In certain implementations of the lighting systems of the present disclosure, the first percentage can be between about 15% and about 25%, between about 16% and about 22%, about 16%, about 17%, about 18%, about 19%, about 20%, about 21%, about 22%, about 23%, about 24%, or about 25%. In further implementations of the lighting systems of the present disclosure, the second percentage can be between about 0.9% and about 1.05%, between about 0.85% and about 0.95%, between about 0.85% and about 0.90%, between about 0.90% and about 0.95%, about 0.90%, about 0.91%, about 0.92%, about 0.93%, about 0.94%, about 0.95%, about 0.96%, about 0.97%, about 0.98%, about 0.99%, about 1.00%, about 1.01%, about 1.02%, about 1.03%, about 1.04%, or about 1.05%. In some implementations, the lighting systems can have a ratio of the first percentage to the second percentage of between about 13 and about 30, between about 15 and about 25, between about 20 and about 25, between about 20 and about 30, between about 18 and about 22, about 13, about 14, about 15, about 16, about 17, about 18, about 19, about 20, about 21, about 22, about 23, about 24, about 25, about 26, about 27, about 28, about 29, or about 30.

Types of User Interfaces and Control Systems for the Control of the Circadian Lighting

Lighting systems that may be used in a computer display system and/or circadian display system in accordance with the principles of the present inventions may be controlled over time to effect the person's circadian cycle throughout the day in different ways. The lighting systems may be automatically or manually adjusted. The lighting systems may be adjusted based on sensor data, activity data, social media data, etc.

In embodiments, as the display systems are installed in the environment of a lighting installation, networking features automatically engage upon powering up one or more the display systems, and the display systems may automatically commission themselves, such as by connecting to an overall control platform and/or to other display systems. Thus, the display systems in an installation may self-commission and self-configure to create a network connection between the display systems in the environment and a remote operator (such as in the cloud). The display systems may configure in a master/slave, ring, mesh, or peer-to-peer network, by which autonomous control features may be engaged in the environment. In embodiments, remote control features may be engaged using the network connection to the platform or other remote operators.

In embodiments, networked communication can be used among components in a deployed lighting installation that includes display systems. Once installed and commissioned, control of the lighting installation may be handed over to an operator of a platform, such as a building owner, occupant, landlord, tenant, or the like. In embodiments, handoff may include using identity and authentication features, such as using keys, passwords, or the like that allow operation of the lighting installation by permitted users. In embodiments, a remote-control interface of the platform may be used by an operator for remote operation of the lighting installation. The remote-control interface may use a lighting project data structure as a source of knowledge about the properties, configurations, control capabilities, and other elements of a lighting installation, so that the same platform used for the design of the lighting installation may be used to control the lighting installation. The remote-control interface may include operational guidance features, such as guiding users through the operation of a lighting installation.

In embodiments, an autonomous control system may be provided for a lighting installation that includes display systems of the present disclosure, by which the lighting installation may control various features of the lighting system, such as based on information collected locally in the environment, such as from one or more sensors 105. For example, the autonomous control system may automatically adjust control parameters for a light source, including but not limited to display systems, to achieve improved adherence to the overall specifications for a lighting installation, may adjust timing variables based on detected usage patterns in a space, may adjust lighting properties based on changes in a space (such as changes in colors paints, carpet and fabrics), and the like.

Under operation, the lighting installation may include an operational feedback system, configured to collect information about the lighting installation, which may include interfaces for soliciting and receiving user feedback (such as regarding satisfaction with the installation or indicating desired changes) and which may include a lighting installation sensor system, such as including light sensors, motion sensors, temperature sensors, and others to collect information about the actual lighting conditions in the environment, activities of occupants within the environment, and the like. Information collected by the lighting installation sensor system may be relayed to a validation system of the lighting platform, such as for validation that an installation is operating as designed, including by comparison of light properties at various locations in the environment with the specifications and requirements provided in the lighting design environment, such as reflected in the lighting project data structure. In embodiments, the variances from the specifications and requirements may be provided to the autonomous control system and/or the remote-control system, so that adjustments may be made, either autonomously or by a local or remote operator of the lighting installation, to enable adjustments (such as to colors, intensities, color temperatures, beam directions, and other factors), such as to cause the lighting installation to better meet the specifications and requirements. The operational feedback system may also capture feedback that leads to revisiting the lighting design in the lighting design environment, which may induce further iteration, resulting in changes to control parameters for the display systems, as well as automated ordering of additional or substitute display systems, with updated installation and operational guidance.

In embodiments, remote control may enable field programmable lighting systems, such as for transitional environments like museums (where art objects change regularly), stores (where merchandise shifts) and the like as well as for customizable environments (such as personalizing lighting in a hotel room according to a specification for a guest (which may include having the guest select an aesthetic filter) or personalized lighting for a workstation for an employee in an office setting. Such features may enable the lighting installation to change configurations (such as among different aesthetic filters) for multi-use environments, multi-tenant environments, and the like where lighting conditions may need to change substantially over time.

In embodiments, a lighting system may include navigation features, such as being associated with beacons, where the lighting system interacts with one or more devices to track users within a space. The display systems and their locations may be associated with a map, such as the map of the lighting space in the design environment. The map may be provided from the lighting design environment to one or more other location or navigation systems, such that locations of display systems may be used as known locations or points of interest within a space.

In embodiments, the lighting installation may be designed for an operation that is coordinated with one or more external systems, which may serve as inputs to the lighting installation, such as music, video and other entertainment content (such as to coordinate lighting with sound). Inputs may include voice control inputs, which may include systems for assessing tone or mood from vocal patterns, such as to adjust lighting based on the same.

In embodiments, inputs may also include inputs from wearable devices, such as enabling adjustment of lighting control parameters (autonomously or with remote or local control features) based on physiological factors, such as ones indicating health conditions, emotional states, moods, or the like. Inputs from wearable devices may be used in the operational feedback system, such as to measure reactions to lighting conditions (such as to enable automated adjustment of a lighting installation), as well as to measure impacts on mood, health conditions, energy, wellness factors, and the like.

In embodiments, the platform may be configured to change settings or parameters for a lighting installation (including but not limited to display systems of the present disclosure, such as by using a custom tuning system) based on a variety of real time data, with a view to having the lighting installation, including display systems included therein, best suit its environment in a dynamic way. In embodiments, data may be obtained that serves as an indicator of the emotional state or the stress level of an environment, and the lighting installation may respond accordingly to that state or stress level. In embodiments, data about the environment may be collected by a wearable device, such as a smartwatch, armband, or the like; for example, data may be collected on acceleration, location, ambient light characteristics, and heart rate, among other possibilities. In embodiments, the data may be provided to the platform for analysis, including using machine learning, such as to observe physiological indicators of stress, mood, or the like under given lighting conditions. The analysis may enable model-based controls (such as where a given mood or state of the users in a room are linked to a set of control parameters appropriate for that state). In embodiments, machine learning may be used; for example, over time, by variation of parameters for lighting objects and fixtures (such as color, color temperature, illumination patterns, lighting distributions, and many others), a machine learning system may, using feedback on outcomes based at least in part on physiological data and other data collected by a wearable device, select and/or promotion lighting installation parameters that improve various measures of stress, mood, satisfaction, or the like. This may occur in real time under control of a machine learning system based on the current conditions of users or the environment. In embodiments, data collected at least in part by a physiological monitor or wearable device may be used as an input to processing logic on a lighting object that changes lighting levels or other parameters to accommodate the ‘emotional state’ of the users in an environment where the lighting object is located. In embodiments, there is memory that retains and manages function with no appreciable drain on the battery.

In embodiments, inputs may include systems that take data harvested from sensors in the lighting installation environment as well as sensors that reflect information about users, such as one or more of physiological sensors (including wearable devices, such as armbands, wrist bands, chest bands, glasses, clothing, and the like), sensors on various devices used by a user, ambient sensors, and the like. These may include sensing one or more of temperature, pressure, ambient lighting conditions, localized lighting conditions, lighting spectrum characteristics, humidity, UV light, sound, particles, pollutants, gases (e.g., oxygen, carbon dioxide, carbon monoxide and radon), radiation, location of objects or items, motion (e.g., speed, direction and/or acceleration). Where one or more wearable or physiological sensors are used, they may sense one or more of a person's temperature, blood pressure, heart rate, oxygen saturation, activity type, activity level, galvanic skin response, respiratory rate, cholesterol level (including HDL, LDL and triglyceride), hormone or adrenal levels (e.g., Cortisol, thyroid, adrenaline, melatonin, and others), histamine levels, immune system characteristics, blood alcohol levels, drug content, macro and micro nutrients, mood, emotional state, alertness, sleepiness, and the like.

In embodiments, the platform may connect to or integrate with data sources of information about users, such as including social networks (Facebook™, LinkedIn™, Twitter™, and the like, sources of medical records (23&Me™ and the like), productivity, collaboration and/or calendaring software (Google™, Outlook™, scheduling apps and the like), information about web browsing and/or shopping activity, activity on media streaming services (Netflix™, Spotify™, YouTube™, Pandora™ and the like), health record information and other sources of insight about the preferences or characteristics of users of the space of a lighting installation, including psychographic, demographic and other characteristics.

In embodiments, the platform may use information from sources that indicate patterns, such as patterns involving periods of time (daily patterns, weekly patterns, seasonal patterns, and the like), patterns involving cultural factors or norms (such as indicating usage patterns or preferences in different regions), patterns relating to personality and preferences, patterns relating to social groups (such as family and work group patterns), and the like. In embodiments, the platform may make use of the data harvested from various sources noted above to make recommendations and/or to optimize (such as automatically, under computer control) the design, ordering, fulfillment, deployment and/or operation of a lighting installation, such as based on understanding or prediction of user behavior. This may include recommendation or optimization relating to achieving optimal sleep time and duration, setting optimal mealtimes, satisfying natural light exposure requirements during the day, and maintaining tolerable artificial light exposure levels (such as during night time). In embodiments, the platform may anticipate user needs and optimize the lighting installation to enhance productivity, alertness, emotional well-being, satisfaction, safety and/or sleep. In further embodiments, the platform may control one or more display systems of the present disclosure in accordance with the user needs of the environment based on this information.

In embodiments, the platform may store a space utilization data structure that indicates, over time, how people use the space of the lighting installation, such as indicating what hallways are more trafficked, and the like. This may inform understanding of a space, such as indicating what is an entry, what is a passage, what is a workspace, and the like, which may be used to suggest changes or updates to a lighting design. In embodiments, sensors may be used to collect and read where people have been in the space, such as using one or more video cameras, IR sensors, microwave sensors. LIDAR, ultrasound or the like. In embodiments, the platform may collect and read what adjustments people have made, such as task lamp activation and other activities that indicate how a lighting fixture is used by an individual in a space. By way of these examples, aggregate usage information may be used to optimize a lighting design and adjust other lighting designs. Based on these factors, a space may be dynamically adjusted, and the lighting model for an installation may be updated to reflect the actual installation.

In embodiments, control capabilities of the display systems may include dynamic configuration of control parameters, such as providing a dimming curve for a light source, including but not limited to a display system of the present disclosure, that is customized to the preferences of a designer or other user. This may include a selection from one or more modes, such as ones described elsewhere herein that have desired effects on mood or aesthetic factors, that have desired health effects, that meet the functional requirements, or the like.

In order to truly achieve circadian action, prolonged exposure may be required, however, a melanopic flux may, in many embodiments, need to be at least 10:1 and in further embodiments, may need to be 20:1, 50:1, 100:1, or a greater ratio. It will be appreciated in light of the disclosure that most conventional systems simply adjust from a warm CCT to a cool CCT, which may only provide a 2:1 or 3:1 ratio of melanopic flux, which may not be enough to provide health benefits. In embodiments, the platform may include spectral tuning targets for display systems of the present disclosure that may optimize this ratio based on local installation environments. These targets, along with adjustments intensity of light (e.g., 4:1) may provide a higher ratio, such as a 10:1 ratio or greater, and thus provide greater melanopic flux ratios.

In a second mode and either in combination with the above mode or not, the platform may support an ability to shift the bias of light in a room. In embodiments, controlled variation of one or more display systems of the present disclosure in a lighting environment can contribute to generating a lighting bias typical of being outside.

In embodiments, various other programmable modes may be provided, such as display system settings where using different combinations of color light sources to achieve a given mixed color output may be optimized for efficacy, efficiency, color quality, health impact (e.g., circadian action), or to satisfy other requirements. In embodiments, the programmable modes may also include programmable dimming curves, color tuning curves, and the like (such as allowing various control interfaces, such as extra-low voltage (ELV) controllers or voltage-based dimmers to affect fixture colors, such as where a custom tuning curve provides a start point, an end point and a dimming and/or color tuning path in response to a level of dimming). In embodiments, programmable modes may use conventional tuning mechanisms, such as simple interpolation systems (which typically use two or three white color LEDs) are dimmable on a zero to ten-volt analog system, and have a second voltage-based input for adjusting the CCT of a fixture between warm and cool CCTs. The display systems as described herein can provide for tunable ranges of color points at various x, y coordinates on the 1931 CIE chromaticity diagram. Because of the wide range of potential white or non-white colors produced by the display systems, they may be controlled by the platform that may specify a particular x, y coordinate on the CIE diagram. Lighting control protocols like DMX™ and Dali 2.0™ may achieve this result.

In embodiments, a programmable color curve for an LED driver may be input, such as through an interface of the platform, or through a desktop software interface, a mobile phone, a tablet app, or the like, that enables a user to define a start and stop point to a color tuning curve and to specify how it will be controlled by a secondary input, such as a voltage-based input (e.g., a 0 to 10-volt input) to the fixture. These may include pre-defined curves, as well as the ability to set start, end, and waypoints to define custom curves. For example, an exemplary color curve can have a starting point around 8000K biased above the black body curve, with the color curve crossing the black body around 2700K, and finishing around 1800K below the black body curve. Similarly, another exemplary curve could be programmed such that the start was 4000K well above the black body, with the end being 4000K well below the black body. By way of these examples, any adjustment would be in hue only, not CCT. Further examples may include a curve that never produces a white color, such as starting in the purple and finishing in orange. In any of these cases, these curves may be programmed into display systems via the interface of the platform, the desktop, mobile phone or tablet. In embodiments, the curves may be designed, saved, and then activated, such as using the secondary (supplemental) 0 to 10-volt input.

In embodiments, a three-channel warm dim mode may be used, such as that described more fully in U.S. Provisional Patent Application No. 62/712,182 filed Jul. 30, 2018, which is incorporated herein in its entirety for all purposes, for target applications where the “fully on” CCT falls between 3000K and 2500K. By way of these examples, as the fixture dims (via ELV control or in response to the 0 to 10-volt input) the CCT may be gradually decreased to between 2500K and 1800K. In certain embodiments, the hue adjustment may all occur below the black body curve. Alternative embodiments may use a cyan channel as described elsewhere herein, either long-blue-pumped cyan or short-blue-pumped cyan, and a red channel as described elsewhere herein, plus a 4000K white channel as described elsewhere herein to achieve a warm dimming mode that allows for adjustment both above and below the black body curve. In some embodiments of the three-channel warm dim mode, the white channel can have a color point within a 7-step MacAdam ellipse around any point on the black body locus having a correlated color temperature between about 3500K and about 6500K.

In certain embodiments, the display systems of the present disclosure can include a 4-channel color system as described elsewhere herein and in U.S. Provisional Patent Application No. 62/757,672 filed Nov. 8, 2018, and U.S. Provisional Application No. 62/712,191 filed Jul. 30, 2018, the contents of which are incorporated by reference herein in their entirety as if fully set forth herein, includes 3000K to 1800K CCT white color points within its range, a programmable mode may be included within the driver that adjusts color with the dimming percentage as well. In some aspects, this may be similar to a conventional control mode, except that the color control would not be on the secondary 0 to 10-volt channel, but may be activated through the primary 0 to 10-volt input channel or ELV controller. In embodiments, the “starting” color point may be the one when the fixture was “fully on.” In embodiments, the “ending” color point may be the one where the fixture is maximally dimmed. It is thus possible to make full range color change, such as purple to orange, which is slaved to the 0 to 10-volt or ELV dimming signal.

In embodiments, an optimized mode may be provided. With a 4-channel color system, there are many ways to create a single x-y point on the CIE diagram. In embodiments, the maximally efficient mode may typically be one that uses the colors that have x, y coordinates closest to the target x, y coordinate. But for best color quality, utilizing a fourth channel (and thereby requiring more light from the color in the opposite “corner”) may help provide a desired spectral power distribution. For the maximum melatonin suppression (for systems hoping to mimic circadian lighting), a higher cyan channel content may be required for CCTs of 3500K and above and minimizing cyan and blue content below 3500K. It will be appreciated in light of the disclosure that conventional systems either require expert users to understand the color balances necessary to achieve these effects (who then implement the color balances channel-by-channel) or are designed for maximum efficiency with color quality as a byproduct.

In embodiments, a digital power system is provided herein (including firmware-driven power conversion and LED current control) that controls a multichannel color system, such as a 4-channel color system, and allows for the inclusion of “modes” which may calculate the correct color balance between the various channels to provide optimized outputs. In embodiments, optimization may occur around one or more of efficacy, color quality, circadian effects, and other factors. Other modes are possible, such as optimizing for contrast, particular display requirements. It will be appreciated in light of the disclosure that this is not an exhaustive list but is representative of potential modes that could be engaged through an interface of the platform (or of a mobile, tablet or desktop application) where a color tuning curve may be specified, such that the curve is used to specify an interface between a controller and the Digital PSU in a display system. In embodiments, these modes may account for actual measured colors for each display system and calculate the correct balance of for the chosen modes, such as based on algorithms loaded into the Digital PSU microprocessor.

In embodiments, machine learning may be used, such as based on various feedback measures, such as relating to mood (stated by the user or measured by one or more sensors), noise levels (such as indicating successful utilization of a space based on a desired level of noise), returns on investment (such as where display systems are intended to promote retail merchandise), reported pain levels, measured health levels, performance levels of users (including fitness, wellness, and educational performance, among others), sleep levels, vitamin D levels, melatonin levels, and many others. In embodiments, the lighting installations including the display systems may be operated or controlled based on external information, such as based on seasonal lighting conditions, weather, climate, collective mood indicators (such as based on stock market data, news feeds, or sentiment indices), analyses of social network data, and the like. This may include controlling a system to reflect, or influence, the mood of occupants.

EXAMPLES

General Simulation Method for Examples 1-13 and 35.

Display systems having three, four, five, and six LED-string-driven lighting channels with particular color points were simulated. For each device, LED strings and recipient luminophoric mediums with particular emissions were selected, and then white light rendering capabilities were calculated for a select number of representative points on or near the Planckian locus between about 1800K and 10000K. Ra, R9, R13, R15, LER, Rf, Rg, CLA, CS, EML, BLH factor, CAF, CER, COI, and circadian performance values were calculated at each representative point.

The calculations were performed with Scilab (Scilab Enterprises, Versailles, France), LightTools (Synopsis, Inc., Mountain View, Calif.), and custom software created using Python (Python Software Foundation, Beaverton, Oreg.). Each LED string was simulated with an LED emission spectrum and excitation and emission spectra of luminophoric medium(s). For luminophoric mediums comprising phosphors, the simulations also included the absorption spectrum and particle size of phosphor particles.

The LED strings generating combined emissions with color points within the long-blue-pumped cyan regions were prepared using spectra of LUXEON Rebel Blue LEDs (LXML-PB01, LXML-PB02) of color bins 1, 2, 3, 4, or 5, which have peak wavelengths ranging from 460 nm to 485 nm, or LUXEON Rebel Cyan LEDs (LXML-PE01) of color bins 1, 2, 3, 4, or 5, which have peak wavelengths raving from 460 nm to 485 nm. Similar LEDs from other manufacturers such as OSRAM GmbH and Cree, Inc. could also be used. The LED strings generating combined emissions with color points within the yellow and violet regions were simulated using spectra of LEDs having peak wavelengths of between about 380 nm and about 420 nm, such as one or more 410 nm peak wavelength violet LEDs, one or more LUXEON Z UV LEDs (product codes LHUV-0380-, LHUV-0385-, LHUV-0390-, LHUV-0395-, LHUV-0400-, LHUV-0405-, LHUV-0410-, LHUV-0415-, LHUV-0420-) (Lumileds Holding B.V., Amsterdam, Netherlands), one or more LUXEON UV FC LEDs (product codes LxF3-U410) (Lumileds Holding B.V., Amsterdam, Netherlands), one or more LUXEON UV U LEDs (product code LHUV-0415-) (Lumileds Holding B.V., Amsterdam, Netherlands), for example.

The emission, excitation and absorption curves are available from commercially available phosphor manufacturers such as Mitsubishi Chemical Holdings Corporation (Tokyo, Japan), Intematix Corporation (Fremont, Calif.), EMD Performance Materials of Merck KGaA (Darmstadt, Germany), and PhosphorTech Corporation (Kennesaw, Ga.).
